Podium Pitch Talk (on-demand & on-site): Utility function based adaptation of virtual RAN (vRAN) – the future of 5G networks

Date/Time: 8 December 2020, Tuesday: 15:40-15:50 (on-site presentation time)
Speaker: Dr Slawomir Pietrzyk, CEO, IS-Wireless

Abstract: This pitch will indicate directions of network composability and adaptability based on intelligent utility function. The 5G specifications with the introduction of elements like: CUPS, SBA, functional option splits has opened towards virtualization of previously “walled garden” deployments of so far physical network functions (PNF). Owing to such features, network functions has become virtualization-friendly (VNF). In combination with the functional splits (e.g. 6, 7.2) and backed up by strong capacity fronthauls (fiber optics, mmWaves) combined with edge cloud based data centers is now going towards low-latency and high-capacity services. The virtualized RAN (vRAN) introduces certain degrees of flexibility. Decomposing vRAN protocol stack into set of disaggregated radio stack functions (CP, UP and CU, DU, RU) leads to novel opportunities of provisioning, operation and management of 5G and B5G networks. The crucial enabler here can be orchestration and intelligent deployment of virtual RAN networks with closed loop feedback. It allows wide range of adaptations (proactive and polymorphic). This way operators enter the new era where software-driven 5G/B5G vRAN networks are becoming composable. Projects like the H2020 Morphemic indicate future paths towards networks provisioning and adaptation based on various criteria (e.g. price, computational cost, performance achievable, etc). The key research directions are polymorphic and proactive adaptation of workloads (including vRAN). The SD-RAN from IS-Wireless enables introducing composability of network deployments and its adaptation.
